Feature management and experimentation platform

Faster and Safer Releases through Experimentation

Engineering teams deploy continuously and monitor the impact of features on technical infrastructure, while product teams control how features are released and their impact on users' experience and business KPIs.

We deliver much more than just switching features on and off

We push the concept of feature flags to the next level,
giving you full control over how you release new features

Feature control at the flip of a switch

Enjoy the flexibility of remote configuration at scale. Managing feature flags on complex and multiple environments can get tricky. With Flagship, organize your flags any way you like, and create any flag type: Boolean, Number, String, Array, Object. Quickly see which user segments are exposed to which flags and their corresponding results. Scale at the pace of your ambition.

Risk-free Deployment

Be confident when rolling out new features

Set deployment intervals, or percentages, to automatically roll out your features over time and monitor their reception with associated metrics. You can also release to specific user segments and later extend to your entire user base if you are happy with the feature. Hit a snag? Deployment automatically rolls back when KPIs dip below a certain threshold. Minimize risk - and headaches - for your team.
Continuous delivery

Separate code deployments from feature releases 

Accelerate your development process by decoupling code deployments from feature releases. Engineering teams deploy code at their own pace, while product teams independently release features when they are ready. They can test in production and gather user feedback while developers focus on their next development cycle.

Staging environments can only go so far

Relying on staging environments to test your code is limited and brings its own challenges, such as keeping both production and staging environments in sync. Moreover, “soak testing” (e.g.: testing a feature with a typical production load), is hard. With feature flags and user segmentation, you can easily see how your code performs using existing monitoring tools and adapt quickly.
Advanced server-side testing

A/B testing for agile teams

Marketing teams rely on client-side testing platforms to run cosmetic changes but - when it comes to advanced scenarios - they end up calling upon developers who need extra flexibility to meet this demand. When code logic is wrapped with feature flags, non technical teams can easily design feature variations using a UI, assign them to groups of users and enjoy the convenience of a statistical engine to measure outcomes. Plus, since it's server-side based, they can run flicker-free A/B tests on any website, app or codebase.

Speed, scale and reliability to the core

Inserting a few IF statements in your codebase is easy, but maintaining a full-featured feature flag management platform requires time, resources and commitment. From data security and safeguards to scalable architecture through a fast decision engine that supports file bucketing users for increased performance and low latency, we make sure we exceed the most demanding technical requirements.
Feature Flag Setup
Multi-channel experiences

Ensure experience continuity

Manage feature flags across web, mobile and server side applications and make sure users who get assigned a specific value for a feature flag on one device get the same one on a different one.

  • Akeneo
    "We were looking for a tool that was adapted to Product Managers, easy to implement and user-friendly. Flagship will allow us to ensure that Product Managers regain control of published features. With the ease of enabling or disabling a feature with a single click, and with all the data we can leverage, I'm expecting some very good results."

  • Oui.sncf
    "Progressive rollout lets us stop or fully rollout a test as soon as it reaches statistical significance without having to wait for a new publication of the app. If the chosen KPIs worsen, we can avoid prolonging a sub-optimal experience. On the other hand, if the test is positive, all of our clients can start feeling the benefits immediately."
